Abstract

This utility model relates to the field of magnetic flaw detection, to devices for non-destructive testing of pipelines, and, in particular, to a magnetic system for an in-pipe flaw detector. The technical effect of the claimed utility model consists in decreasing mutual influence of main belts of magnetic modules and improving uniformity of magnetic field distribution in circumferential and longitudinal directions. The magnetic system for transverse magnetization having fixed magnetic modules and designed for an in-pipe flaw detector consists of two main and four additional belts of magnetic modules, which are arranged on two magnetic conductors connected with a non-magnetic insert. Each magnetic module consists of permanent magnets and wire brushes that transfer a magnetic flux into the pipeline wall. Magnetic modules that are adjacent to each other in a belt have opposite directions of a magnetic field in an interpolar space. The main poles of magnetic modules are angularly offset relative to each other. The additional belts of magnetic modules are arranged at the edges of the main belts of magnetic modules, two additional magnetic modules being arranged between the belts of main magnetic modules and serving for compensating mutual influence of a magnetic field generated by the main magnetic modules and for decreasing non-symmetry of the magnetic field, which is caused by close location of the main poles. Each additional belt of magnetic modules serving for correcting non-symmetry of the field is angularly offset relative to a main magnetic belt.

Description

  • This utility model relates to the field of magnetic flaw detection, namely to devices used for non-destructive testing of pipelines, and, in particular, to a magnetic system of an in-pipe flaw detector.
  • An in-pipe flaw detector is known ( RU Patent No. 2225977 , publ. 27.05.2003, IPC G01M3/08, F17D5/00, G01N27/72), which sensors are arranged in respective holders, each holder being fixed in the flaw detector housing with the use of a pair of arms capable of rotating in a plane crossing the axis of symmetry of the magnetic flaw detector. The invention enables to improve the flaw detector capacity of passing through long, curved, narrowed regions in a pipeline and to reduce a volume of data not suitable for identifying flaws in a pipeline wall; but, due to irregular distribution of a magnetic field in circumferential and longitudinal directions, this flaw detector provides errors while determining flaw dimensions.
  • An in-pipe flaw detector is known ( RU Patent No. 2248498 , publ. 29.10.2003, IPC F17D5/00, G01M3/00), which non-destructive testing sensors are arranged in respective sensor holders, each sensor holder being fixed in the flaw detector housing with the use of at least two arms. On the arm or the sensor holder at the flaw detector nose portion, one or more elements are arranged that are made capable of bending toward the tail portion in a plane passing through the axis of symmetry of the flaw detector. The use of this flaw detector enables to improve the flaw detector capacity of passing through long, curved, narrowed regions in a pipeline and to reduce a volume of data not suitable for identifying flaws in a pipeline wall; but, due to irregular distribution of a magnetic field in circumferential and longitudinal directions, this flaw detector provides errors while determining flaw dimensions.
  • The closest prototype for the claimed utility model is a magnetic measuring system with transverse magnetization for an in-pipe flaw detector ( RU Patent No. 109863 , publ. 27.05.11, IPC G01N27/83), which consists of identical magnetic modules for transverse magnetization in the form of two annular belts arranged symmetrically relative to the central axis of a hollow cylindrical base, one after the other, on spring-loaded articulated arms coupled to the hollow cylindrical base, meanwhile one or more additional permanent magnets in the form of a rectangular parallelepiped are arranged in the interpolar space of each magnetic module for the purpose of improving uniformity of magnetic field distribution.
  • The technical effect of the claimed utility model consists in reducing flaw detection errors due to mutual influence of the magnetic module main belts, thus improving uniformity of magnetic field distribution in circumferential and longitudinal directions.
  • The technical effect of the claimed utility model is achieved due to the fact that the magnetic system for transverse magnetization having fixed magnetic modules and designed for an in-pipe flaw detector consists of two main and four additional magnetic module belts arranged on two magnetic conductors connected by a non-magnetic insert. Each magnetic module consists of permanent magnets and ferromagnetic elements transferring a magnetic flux to the pipeline wall. The adjacent magnetic modules in a belt have opposite directions of a magnetic field in the interpolar space. The main poles of the magnetic modules are angularly offset relative to each other by the angle ϕ: ϕ = 180 ° / N ,
    Figure imgb0001
     where N is a number of magnetic modules in a single belt. Sensors, which register any change in magnetic induction, as caused by a change in the pipeline wall thickness, are arranged between magnetic poles along the length of a pipeline circumference.
  • The additional belts of magnetic modules are arranged at the edges of the main belts of the magnetic modules; two additional belts of magnetic modules are arranged between the main belts of magnetic modules and serve for compensating mutual influence of a magnetic field generated by the main belts of magnetic modules and for decreasing non-symmetry of a magnetic field which symmetry is caused by close location of the main belts of magnetic modules. Each additional belt of magnetic modules is angularly offset relative to a main magnetic belt by an angle α<90° for the purpose of correcting non-symmetry of a magnetic field.
  • In order to reduce errors, a pipeline material is magnetized to the condition of technical saturation, since with an increase in magnetization intrinsic noises of a pipeline material as well as sensitivity of the flaw detector measuring system to a pipeline material are reduced.
  • In a development of the utility model, the magnetic system for transverse magnetization having fixed magnetic modules for an in-pipe flaw detector may be made of a single section and of a plurality of sections, and in this case it may comprise two or more main belts of magnetic modules and four or more additional belts of magnetic modules that are arranged on two or more magnetic conductors, and in this case a cardan joint may be substituted for the non-magnetic insert.
  • As a result, flaw detection errors are reduced due to decrease in mutual influence of the main belts of magnetic modules and improvement of magnetic field distribution in circumferential and longitudinal directions.
  • Fig. 1 shows a general view of the magnetic system for transverse magnetization having fixed magnetic modules and designed for an in-pipe flaw detector.
  • The following designations are used in Fig. 1:
    • 1.- main belt of magnetic modules;
    • 2.- additional belt of magnetic modules;
    • 4.- non-magnetic insert.
  • Fig. 2 shows cross-sectional views of the main magnetic modules used in the magnetic system for transverse magnetization having fixed magnetic modules and designed for an in-pipe flaw detector.
  • The following designations are used in Fig. 2:
    • 3.- magnetic conductor;
    • 5.- permanent magnet;
    • 6.- elements made of a ferromagnetic material.
  • Fig. 3 shows cross-sectional views of the additional magnetic modules used in the magnetic system for transverse magnetization having fixed magnetic modules and designed for an in-pipe flaw detector.
  • The following designations are used in Fig. 3:
    • 3- magnetic conductor;
    • 5- permanent magnet;
    • 6- elements made of a ferromagnetic material.
  • The magnetic system for transverse magnetization having fixed magnetic modules and designed for an in-pipe flaw detector (Fig. 1) consists of two main belts of magnetic modules 1 (Fig. 1) and four additional belts of magnetic modules 2 (Fig. 1), which are arranged on two magnetic conductors 3 (Fig. 2 and Fig. 3) connected with a non-magnetic insert 4 (Fig. 1). The magnetic modules 1 and 2 (Fig. 1) consist of permanent magnets 5 (Fig. 2 and Fig. 3) and elements 6 made of a ferromagnetic material (Fig. 2 and Fig. 3).
